Rifleman, Acanthisitta chloris, at Flora Saddle, New Zealand

Description: The Rifleman or Titipounamu in Maori (Acanthisitta chloris) is New Zealand's smallest endemic bird with fully grown adults reaching around 8 cm. This insectivorous passerine bird belongs to the Acanthisittidae family, also known as the New Zealand wrens, of which it is one of only two surviving species. The Rifleman resembles a wren in form but is not related to the family of true wrens, Troglodytidae, nor the fairy-wrens of Australia.
